To all whom 'it may concern:

of the Netherlands, residing at Vryenban, near Delft, Netherlands, have invented certain new and useful Improvements in Embroidering-Machines, of which the following is a specification.

The invention relates to a embioideringmachine -for automatically sewing characters, words, figures, numbers, etc., in woven materials and the like.

ln using a machine according to the inonce subsequently in different pieces of material, whereby the machine needs to be adjusted but once. lt is also possible, in adjusting the machine but once, to sew-a predetermined character, ligure, word or number in different pieces of material; if desired a series of characters -can also be sewed with the machine.k Y

Thermachine according to the invention consists in the combination of a shoemakei'ssewing-machine known in itself, with a device automatically effecting the angular adjustment of the known feed claw of the sewing-machine, according to the character, figure, word or number to be sewed in the piece `of material, which device, after the vmark hasbeen finished, is automatically rethe invention consists of a rotatable, gradusired angular adjustment. vention marking occurs very fast, whereby va shaft l() (Fig.` l).

transmitted to the feed claw of the sewingmachine, of a pin, alternatively falling in those recesses or on those teeth and moved back again, impart to the feed claw the de- In order, after themark has been sewed in the piece of material to return the drum to its initial position, whereby at the saine time the machine is stopped, the drum, according to the invention, maybe provided with adjustable stops or notches, which, after the mark has been finished, effect the stopping of the sewing-'machine and the returning of the drum in its initial position.

The invention will be fully explained hereinafter by the aidv of the accompanying drawings in which: l

Figure l Vis a top View vof the machine. Fig. 2 a side elevation with parts broken away.

Fig. 7 is a fragmentary side elevation,

' showing the gearing operated by the movements of the pin-operated rod for operating the claw.

The machine, mounted on the frame, is driven by means of a pulley l on a horizontal shaft 2. By means of a sliding clutch Fig 3 a section on the line 3--3 of Fig. l,

3 the shaft 2 can be coupled with a hollow shaft t` surroundiiig the shaft 2. On the shaft 4 is fixed a bevel-wheel 5 engaging a ievel-wheel on a shaft 7. The rotation of 'the shaft 7 is transmitted by means of a cani-disk 8 to a lever 9, fixed on one'end of of shaft 10 are transmitted by-means of a lever ll, secured to one end of the shaft 10 and yhaving its vother end connected with the horizontally slidable rod .12. The rod 12 transmits its movements to a vertical pin 13 by means of a rack 20 (Fig. 3) onv the rod The angular rotations downward as soon as'the lever 9'is freed from the cam of the cam disk. The function el after.

First however it must be'inentioned that also'the movement oa cylinder or drum 1G (Fig. 4)"isfderived from theshalt 7 by means 'i a crank 14:, a rod 15, a lever 17 freely rotatable about the aXis of the drinn rnd a pawl 1S connected with the lever 17 and engaging a ratchet-wheel 191ixe'd onthe drum-shalt. Each revoli'ition of the shaft 7 with cam disk 8 causes a rotation of the drum ot' one tooth of the ratchet-wheel.

rfhe drum carries a plurality oi adjacent rows ejf blocks GS'bein'g slidable lengthwise ifi/.ir example in dove-tailed longitudinal ,grooves or' the drimsurl'ace. This plurality oitblocksserves tov make various character-or li gure combinations. Each la o'ck is provided with one'or more recesses 69 (Fig.

et different depth between which are'povided teeth of diiter'e'nt height'. The pin 13 above the drum can be brought intoengagenient with these recesses and teeth. Accorf. ing to the pin falling into a more or less deep recess or on a tooth between two recesses, the rod 12 will be moved more or less tea the right by the spring. Thesev movements of the rod 12 are transmitted in a manner to be described hereinafter to the leed ciaw of the sewingimachine G3 and impart to this claw the desired angular ladiustment. It may be mentioned here, that the sewingfmachine 63 is driven by means of a i'-liain-pulley @si on the shait il, a chain 65 and a chain-pulley G6 on the shaft 7) 'ot the firewiiig-machine, so that the latter is stopped hv disengaging the clutch 3.

The downward movements oll the pin 13 determine -the angular adjustments of the reed claw to be obtaine'c. Owing to the tact that these downward Amovements are determined by the blocks and that the latter are shaped in correspondence with the ligure, character, etc., to be sewed. the 'feed claw of the sewing-machine receives such an angular "irresponding adjustment that the desired ire. character. etc., 'is sewed in `a piece o1 material orthe like.

Tt will be clear, that` the 'cam disk S and the crank 14 must be adjusted with respect to each other in such a manner that the pin "9.- is kept lifted when the ratchet wheel 19 moved forwardly by`a tooth by thepawl v13 and consequently the yblocks are rotated correspondingly.

A spring wat the pin 13 will be fully described hereini reliance4v 'lie movements to the lett and to the right Y ofthe `rod 12 can beltransmitted directly to l, 3 and 6) provided at its upperside with Yan oblique cam 25`and at'its lowerside with a vertical rib 2G parallel with the rod 12. The block 24 is slidable perpendicular tothe rod 12in a recess 27 ot an enlarged part of this'rod. Y A movement ofthe rod 12 causes the cam 25 to slide through an oblique slot 23 of 'an enlarged part 29 of a rod 30, arranged perpendicular'tothe rod 12 and lslid- :ihle longiti'idinally, said rod 30 Ythen being trictionally held against displacement.

The slot 28 is arranged at 'a considerably smaller angle with the rod 12 than with the rod 30, so that a movement to theright ot the rod 12 by the spring a will displace the block in the recess 2.7, whereby -the cam slides through the slot 28. The block consequently is moved out of its middle-positionfthat4 is with the cam in a vertical plane through the axis 'ofthe rod 12) by amovement to the left as well as to the right.

the feed claw Vof the sewing-machine by means of aV gearing 71 is effected by the device shown in Fig. 5.

This device consists of a cam disk 31, driven bythe shaft 2. with two cams 32 and 33 in different vertical planes, said cams acting respectively on the'ends of weighted arms 34 and 35 of 4anglelevers, the other arms 36 and 37 of which act on the'rib 26 ofthe block 24 between the free ends ot .said arms. A spring C connected with the arms 34 and 35 Vholds said armsin engagement withthe cams 32 and 313. The cams are'so shaped and the angle-levers are arranged insuch a manner that'the arms 36,

The displacement Aof the rod 30, acting on Yartisanat.

the feed claw of the sewing-machine, the drum with the blocks is rotated a certain angle by the pawl 18 and, for sewing this character, figure, word or the like again,

Vmust be returned in its initial position.

This is effected automatically. For this purposev a pulley 38 with a weight 39 is fixed on the drumshaft (Figs.v 1 and 4). For rotating back the drum, the pin 13 must be kept in its lifted'position. The pawl 18 also must be kept lifted out of engagement with the ratchet wheel 19. A counterpawl 40 arranged to engage the ratchet wheel 19 kin order to prevent the drum from rotating backward must alsobe lifted out of engagement with the ratchet wheel. l

For keeping the pin 13 uplifted, stopping Vthe machine and lifting the two pawls 18 `and 4() the following device is employed: VA block G8 is provided with an adjustable l.projection 41. V This projection is secured projection 45. This is the position in which the clutch 3 is coupled, the machine is running and the drum is moved forward by the pawl 18. Y

Y The projection 41 in engaging the tail 42 of the lever 44 will turn the latter, so that it falls against the projection 46 and consequently will turn the sector 47.V

Together with the lever 44 a sector 72 fixed on 'the shaft of the lever 44 is rotated. This sector lifts the 'counterpawl 40 by means of a connecting rod 48 and a rod 49 on the axis of the pawl, connecting 48 with Vsome play with the pawl.

An elongation 50 ofthe sector'72 when the sector rotates presses on the tail 51 of the pawl 18, so that this pawl also is lifted.

The sector 47 is articulated at '52 to one end of a rod 53 (Fig. 3), the other end of which vis articulated to a rod 55 fixed on the same shaft as the lever 54 of the clutch 3.

In rotating the sector 47 to the right the clutch 3 consequently is disengaged and the machine is stopped. On the same shaft as thejrodis fixed a lever 56, theend of which is articulated'to an arm of a doublearmed lever 58,' rotatable at 57, thev other arm of which. in rotating to the left, comes into engagement with a stop 59 of the rod 12 so that this stop and consequently the rod 12 are moved to the left and the pin 13 is lifted out of engagement with the blocks of the drum. The drum now is freed from the pawls 18 and 40 as well as from the pin 13, and is rotated back in its initial position by the weight 39. After the lreturn of the drum to initial position a second adjustable stop 60 on the Vsurface of the drum in a vertical plane other from that ofthe stop 41 comes into engagementwith an arm 73 on the shaft of the lever 44 and turns the latter back against the stop 45. ln order to prevent the automatical coupling of the clutch 3 under the action of the lever 44 with weight on the stop 45 of the sector 47, a stop 61 is arranged in the path of the lower end of the lever 54 (Fig. 3), said stop keeping said lower end in the disengaged position. This stop can be moved by hand, by meansfof a lever 62 under the action of a weight or spring, out of the path of the lower end of the lever 54, so that the clutch again is coupled, the rod 12 again is moved to the right, the pin is brought into engagement with a block and the pawls are coupled.
